Thanks, everyone, for all of your suggestions.  What really helped was running the 1st layer at 25% of the normal speed. With that, even with the bed not PERFECTLY level, everything is sticking just fine.  Despite other's comments, my kapton is working perfectly (although I have only done a dozen prints, or so).  I'm now running the bed at 85 and the extruder at 185

Very glad to hear things are up and running.

I've updated the start g-code thread to address the original problem from this thread:

As for the sticking, level the bed, fix the z-offset, and perhaps use some hairspray.

Comprehensive!

Many times I would make a new profile in Slic3r and hit slice, without having selected the new profile in Repetier which would just give me the same thing I had before.

My second printing attempt was the filament bushing, which printed perfectly.  My third attempt was a pair of the bed adjustment knobs, but all I ended up with was a ball of plastic string.  I tried again, and noticed that while the central disks printed correctly, there were a few stray lines along each side that were not sticking to the bed.  Assuming that this might be support structures, I removed support, but the problem persisted.  Any idea what is wrong here? The bed is set to 100, but probably is closer to 95

I would attach the images in line, but I am not sure how that is done

Is there any way to set the custom GCode up so that it starts heating the bed, waits for the bed, starts heating the extruder, waits for the extruder, and then goes?  It takes 15 minutes for the bed to heat, but only 3 minutes for the extruder to heat.  I don't want the extruder sitting there hot for 12 minutes if I can avoid it.

I modded a part of the start gcode to ..

M190 S95 ; set and wait for bed temp of 95 to be reached
M140 S100     ;then set bed to 100
M104 S200 ; set extruder temp and start heating
G90; set absolute coordinates
G1 Z5 F300 ;move platform down 5mm
G1 X10 Y10 F3000 ;move to front left corner
M109 S200; wait for extruder temp to be reached

so it waits till 95 is reached, it gets there every time but will only get to 100 if the case is on, so I then set it for 100 but do not wait for it, turn on the extruder to 200 but do not wait, home all the axis, with the Z right down the bottom it takes a little while to lift up so the extruder temp can get a start on the heating before this .. then it does the shift to front left and waits there over the bed till full heat is obtained.
So since the bed has still been heating that last bit while the extruder heats its closer to the 98 mark by the time it starts printing. The trick is to get the extruder on just a little before the bed is up to temp, then there is no waste of time waiting for bed and then extruder and the extruder is not sitting there cooking, it goes as soon as the extruder is up to temp even if the bed is still a little low.

see the modified start gcode thread for the rest of it.

I try to have it with 5C of the print temperature when I start.  I usually extrude a little first to get it primed, and don't want it waiting above the bed, oozing more plastic while it reaches temp.

I finally gave up on all of the extruder temperature commands and commented them out.  I ensured that the bed and extruder were up to temperature, manually, and then started the job.  It seemed to go OK (some strings, but after all, it was the first print).

Is there any way to set the custom GCode up so that it starts heating the bed, waits for the bed, starts heating the extruder, waits for the extruder, and then goes?  It takes 15 minutes for the bed to heat, but only 3 minutes for the extruder to heat.  I don't want the extruder sitting there hot for 12 minutes if I can avoid it.

Is everyone managing the bed temperature manually (heating it up before you start printing)?

What custom GCode are you using presently?

Thanks!

M104 S195,195,195 ; set extruder temp and start heating
*snip*
M109 S195,195,195; wait for extruder temp to be reached

This is the problem. The software is trying to set the temp for three extruders. You are using my new g-code, but Repetier-Host  0.84 breaks it.

Where the code asks for [first_layer_temp], substitute in your 195.

Watch the video in my thread to see what the extrude anchor does.
